Abstract

Instrument for indicating decompression pauses, particularly for underwater dives, characterized by the fact that it comprises two chambers, one of which contains, at least partially, compressible fluid and the other is deformable and is externally subject to hydrostatic pressure, a conduit that puts said chambers in communication, and which includes means capable of creating a pressure drop in the passage of fluid from one of the chambers to the other and means to indicate the pressure of the fluid contained in said non-deformable chamber, with respect to at an initial reference pressure constituted by the pressure of the air at the surface of the liquid in which the immersion is carried out.
